What are the unqualified boiler water quality of biomass boilers? In recent years, with the increase of smog, the state has taken environmental emergency actions. The State Council’s Air Pollution Prevention Action Plan issued in September 2013 strictly controls the “two high†industries and coal consumption. The use of small and medium-sized coal-fired boilers will promote the rapid development of biomass boilers. The water quality of biomass boilers has also attracted people's attention. In the operation of biomass boilers, the quality of water is directly related to boiler operation. As well as the quality of steam and hot water produced, Zhengguo is a well-known biomass boiler manufacturer in China. It analyzes the following unqualified biomass boilers: 1. Water quality pH and alkalinity are too high: if it is due to If the excess alkalinity (ie, the difference between alkalinity and hardness) of the biomass boiler feed water is high (>2mmol/L), appropriate alkali reduction treatment should be adopted; if the raw water alkalinity is not high, it is If too much alkali is added or the sewage is not enough, the dosing should be reduced or suspended, and the boiler blowdown should be strengthened. 2. The pH value and alkalinity of the water are low: the cause of this phenomenon is that the pH value and alkalinity of the water itself in the boiler are low, and if the boiler discharge amount is too large, the alkalinity of the water will be low. It should be properly controlled. 3. The water supply hardness and the chloride ion content are too high: if the water supply hardness is too high, it should be regenerated in time and the ion exchanger should be operated correctly. The backwash valve and the water supply bypass valve should be checked frequently, and the leak should be replaced in time; if it is chlorine Excessive ion content enhances biomass boiler blowdown.
